Li-Fi (Light Fidelity) is an optical wireless communication technology that transmits voice, video, data, and other signals modulated at high speed by LED light. It has the advantage of being free from radio interference and can be used in high-frequency restricted environments. While organic LED (OLED) lighting is being put to practical use, visible light communication (VLC) using OLEDs with bandwidths exceeding 200 MHz has been reported. In this report, transient EL characteristics were measured when a pulse voltage train was superimposed on the applied voltage of polymer LEDs to study basic Li-Fi characteristics of OLEDs.
